The Prerogative of Jealousy
Jesus made it very clear that He wouldn’t play second fiddle to anyone.
“If anyone comes to Me, and does not hate his own father and mother and wife and children and brothers and sisters—yes, and even his own life, he cannot be My disciple. Whoever does not carry his own cross and come after Me cannot be My disciple.” [Lk. 14:26-27] [my emphasis]
[μισέω: hate, despise; disregard, be indifferent to]
On the other hand, He never suggested that any of His disciples arbitrarily loath their family members either. He did, rather, use hyperbole often enough to make His point. And this time, it was simply about prioritizing relationships.
But I think it’s not enough just to honor the commandments of a jealous God [Ex. 34:14, Deut. 4:24, 5:9, 6:15]. I also believe it’s important to understand why it’s necessary for Him to be that way.
The New Oxford American Dictionary defines jealous as an adjective used to describe emotions which are “fiercely protective or vigilant of one’s rights or possessions.” The line between jealousy and covetousness is very visible here when we understand the latter as an unjustified or lawless desire.
So, even though both of these emotions emerge from a desire to satisfy a passion to either possess or connect with something or someone, jealously is the only defensible sentiment of the two, because it’s a legitimate response to protect rightful ownership.
And make no mistake, God is the rightful owner of the flock He purchases with His own Son’s blood. [Ac. 20:28; Rev. 5:9-10] But, remember, no man can be purchased against his will. Jesus said, “If anyone comes to me…” Why would He be “fiercely protective” of something He doesn’t own?
He owns me because I chose to love Him. And it seems to me that one way He reciprocates His love for me [His possession] is by being jealous if I don’t love Him more than life itself.
So, am I justified drawing the same jealous lines in the sand like Jesus did?
Only if I know how to love what’s rightfully mine.

Salute, son of man; once again you hit the target of the Gospel and its many applications. “All Scripture is God-breathed and is valuable for teaching the truth, convicting of sin, correcting faults and training in right living”… please continue in you labor, as your page is always a welcomed sight!
